JS1-6V-F General Purpose Relay SPDT 10A 6VDC Equivalent & Substitute Parts

Part Overview

The JS1-6V-F is a general purpose relay manufactured by Panasonic Electric Works, featuring a single pole double throw (SPDT) contact configuration with a 6VDC coil and 10A contact rating. This through-hole mounted relay is designed for standard switching applications requiring sealed operation and non-latching coil behavior.

The JS1-6V-F has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JS1-6V-F is determined by the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be SPDT (1 Form C) to maintain switching functionality
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct socket or board connection
• Coil Type: Must be Non Latching to match operational behavior
• Operating Temperature Range: Must encompass or exceed the -40°C ~ 70°C specification

The ALQ106 meets these core substitution criteria while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The ALQ106 is a suitable substitute for the JS1-6V-F based on the following factors:

Compatibility: Both relays share identical coil voltage (6VDC), contact form (SPDT), mounting type (Through Hole), and termination style (PC Pin), ensuring mechanical and electrical compatibility in existing designs.

Product Status: The ALQ106 maintains active product status with confirmed inventory availability (1959 pcs), whereas the JS1-6V-F is obsolete. This transition ensures long-term supply chain viability.

Compliance: Both parts are RoHS compliant. The ALQ106 carries ROHS3 compliance and holds multiple approval certifications (CQC, cURuus, VDE), providing enhanced regulatory coverage.

Operating Conditions: The ALQ106 supports an extended operating temperature range (-40°C ~ 85°C) compared to the JS1-6V-F (-40°C ~ 70°C), offering improved thermal performance.

Design Considerations: The ALQ106 exhibits a reduced contact rating (5A versus 10A) and lower maximum DC switching voltage (30VDC versus 100VDC). Applications requiring the full 10A current capacity or 100VDC switching capability must evaluate whether the ALQ106 meets load requirements. Increased coil current (66.7 mA versus 60 mA) and extended switching times (20 ms versus 10 ms) should be assessed for timing-critical circuits.

Frequently Asked Questions (FAQ)

Q: Can the ALQ106 directly replace the JS1-6V-F in all applications?

A: The ALQ106 is mechanically and electrically compatible for standard switching applications. However, applications requiring the full 10A contact rating or 100VDC switching capability must confirm that the ALQ106's 5A rating and 30VDC maximum DC switching voltage are sufficient for the intended load.

Q: What are the key differences between these two relays?

A: The primary differences are contact rating (10A versus 5A), maximum DC switching voltage (100VDC versus 30VDC), switching times (10 ms versus 20 ms), and contact material composition (Silver Tin Oxide versus Silver Nickel). The ALQ106 offers an extended operating temperature range and active product status.

Q: Are there packaging differences between the JS1-6V-F and ALQ106?

A: The JS1-6V-F is supplied with standard packaging, while the ALQ106 is packaged in boxes. Both use PC Pin termination for through-hole mounting, ensuring compatibility
